The big news
Imagine scanning any street stall's PromptPay QR and paying from your U-Topia balance in seconds. Snap-to-Pay is designed so crypto travels as baht: ahead of time, U-Bot converts the user's own coins through a licensed bridge into a baht Spending Wallet, choosing the cheapest legal route. At the stall, you scan, U-Bot shows a plain preview and checks for fake stickers, and you approve with one tap. Spending limits are enforced by a smart contract on Avalanche, and the shop always receives baht.

What it does
A prototype U-Bot hand-off flow that pre-funds a baht spending wallet and pays PromptPay QR codes, with fake-QR checks and a Permission Card spending-limit contract on Avalanche. The front end is a React 19 and TypeScript rebuild of the U-Topia dashboard; built with Next.js, TypeScript and Solidity.
